With one plate (fig. i) SUMMARY The bacteria present in the oocytes and follicle cells of Blatta orientalis Linn, were studied by means of electron microscopy. Bacteria are present in the follicle cells surrounding young oocytes, from where they invade the peripheral ooplasm. Each bacterium in ...
Above: a simplified model of an animal cell with a quarter cut-away to show some of the main parts. Click on the thumbnail below to see a fully labelled version. However, the items are coloured coded so it is not necessary to
First, we demonstrate trapping of polystyrene microspheres 5 mm above the surface of the chip and calibrate the trap force. Next, we show tweezing of polystyrene microspheres in one dimension by non-mechanically steering the trap by varying the input laser wavelength. Finally, we use the OPA ...
Cultured meat production has emerged as a breakthrough technology for the global food industry with the potential to reduce challenges associated with environmental sustainability, global public health, animal welfare, and competition for food between humans and animals. The muscle stem cell lines current...
Figure 7. This electron micrograph shows a mitochondrion through an electron microscope. This organelle has an outer membrane and an inner membrane. The inner membrane contains folds, called cristae, which increase its surface area. We call the space between the two membranes the intermembrane spac...
Most tumor cells undergo apoptosis in circulation and at the metastatic organ sites due to host immune surveillance and a hostile microenvironment. It remains to be elucidated whether dying tumor cells have a direct effect on live tumor cells during the
Adipose-derived stem cells (ADSCs) have been extensively used in preclinical and clinical trials for treating various diseases. However, the differences between ADSCs from lean individuals (L-ADSCs) and those from obese individuals (O-ADSCs) have not bee
microscope with motorised stage. The gaps between each pad in the device prevented unwanted merging of liquid drops and thereby eliminated cross contamination between samples. On this multi-pad device, we found that cells on flat gel pads often aggregated into massive clumps, which could not be ...
Hemicelluloses are an abundant source of biomass, but are difficult for microbes to utilise. Here, authors develop a synthetic extracellular metabolic pathway via the enzyme display on the surface of engineered bacteria, demonstrating efficient conversion of hemicelluloses into high-value products and el...
